"Chirpons": one-dimensional phase singularities as atypical local oscillations
Enrique G. Neyra, Laureano A. Bulus Rossini, Fabián Videla +2
In this work, phase singularities embedded in a wavepacket are shown to act as sources of atypical localized oscillations when the packet interacts with a linear system. We refer t…
Free temporal evolution of a superbandwidth wave packet: The quantum tale of the hare and the tortoise
Enrique G. Neyra, Marcelo F. Ciappina, Lorena Rebón
Can the interplay between quantum mechanics and classical optics offer new perspectives on wavepacket dynamics? Building on this connection, we show that local momenta with both su…
Above-threshold ionization by polarization-crafted pulses
Camilo Granados, Enrique G. Neyra, Lorena Rebón +1
Coherent light has revolutionized scientific research, spanning biology, chemistry, and physics. To delve into ultrafast phenomena, the development of high-energy, high-tunable lig…
Superbandwidth laser pulses in a dispersive medium: oscillating beyond the Fourier spectrum with unexpected propagation features
Enrique G. Neyra, Laureano A. Bulus Rossini, Fabián Videla +2
The concept of superbandwidth refers to the fact that a band-limited signal can exhibit, locally, an increase of its bandwidth, i.e., an effective bandwidth greater than that predi…
Twisting attosecond pulse trains by amplitude-polarization IR pulses
Enrique G. Neyra, Fabian Videla, Demian A. Biasetti +2
Natively, atomic and molecular processes develop in a sub-femtosecond time scale. In order to, for instance, track and capture the electron motion in that scale we need suitable `p…
Principal frequency, super-bandwidth, and low-order harmonics generated by super-oscillatory pulses
Enrique G. Neyra, Demian A. Biasetti, Fabián Videla +2
An alternative definition to the main frequency of an ultra-short laser pulse, named principal frequency (), was recently introduced in E.G. Neyra, et al. Phys. Rev. A 103, 05…
Effective super-bandwidth in laser pulses
Enrique G. Neyra, Demian A. Biasetti, Pablo Vaveliuk +4
We present here a theoretical analysis of the interaction between an ideal two-level quantum system and a super-oscillatory pulse, like the one proposed and successfully synthesize…
Simple interferometric setup enabling sub-Fourier-scale ultra-short laser pulses
Enrique G. Neyra, Gustavo A. Torchia, Pablo Vaveliuk +1
In this work, we have developed a method to generate ultra-short pulses below the Fourier limit, extending the concept previously worked in reference 1 for generating sub-diffracti…
Principal frequency of an ultrashort laser pulse
Enrique G. Neyra, Pablo Vaveliuk, Emilio Pisanty +3
We introduce an alternative definition of the main frequency of an ultrashort laser pulse, the principal frequency . This parameter is complementary to the most accepted and w…
High-order harmonic generation driven by inhomogeneous plasmonics fields spatially bounded: influence on the cut-off law
E. Neyra, F. Videla, M. F. Ciappina +4
We study high-order harmonic generation (HHG) in model atoms driven by plasmonic-enhanced fields. These fields result from the illumination of plasmonic nanostructures by few-cycle…
High-order harmonic generation driven by chirped laser pulses induced by linear and non linear phenomena
E Neyra, F Videla, J A Pérez-Hernández +3
We present a theoretical study of high-order harmonic generation (HHG) driven by ultrashort optical pulses with different kind of chirps. The goal of the present work is perform a…
